The operation of the
Burgess Magna-Vac
Degasser®
is
both effective and
efficient. The gas-cut
mud is drawn into the
degasser by a vacuum
created by a
regenerative
vacuum/blower. The mud
enters the vacuum
chamber of the degasser
through a rotating
tubular body that has
rectangular windows in
its wall. Mud
accelerator vanes,
located within the rotor
near the windows,
radially spray the mud
outward at a high
velocity (i.e., 20 feet
per second) across the
degasser's vacuum
chamber impinging it
against the outside wall
of the circular vessel.
The agitation and
turbulence created by
this constant impinging
action allows the oxygen
and gas to separate from
the mud.
The vacuum/blower then draws
the released gases from the vacuum chamber and
discharges them away from the rig at a safe
distance. The degassed mud flows downward into the
lower section of the degasser where it is evacuated
by an internal center-vented centrifugal pump which
prohibits gas-locking.
The self-contained degassers
are normally supplied with a 3600 Revolutions Per
Minute explosion-proof motor with approval for use
in hazardous locations. All voltages and frequencies
are available upon request. Hydraulically-powered
units are also available.
Efficiency = Savings
The Burgess
Magna-Vac Degasser® economically
removes gases and oxygen and helps keep the drilling
mud at a desired weight. Additionally, the unit can
be used as a mechanical oxygen scavenger, extending
the life of the drill string by reducing corrosion.
Quick Installation
The Burgess
Magna-Vac Degasser® is
easily installed on top
of the mud tank with
rigid piping. It's as
simple as that!
Field Proven
The
Burgess
Magna-Vac Degasser®
underwent extensive
testing before being
brought on the market
and has been in the
field for years.
Installations like this
one have had years of
proven performance and
reliability all over the
world.
